-We saw this in science fiction movies: someone pulls out of the space ship and thrown into the vacuum in this broad space without injured , many of the movies explain incorrectly but the truth is that  the exposed person without protective suit to the vacuum may be the strangest and more exotic than you imagined.



1-outside Distension:
 No doubt you remember Veroka Salt in the movie "Willy Wonka and the Chocolate Factory" when  turned into a giant blueberry, the effect of space on the human body would be similar. Without the  presence of atmospheric pressure for the planet, the water that make up 70 percent of our bodies will  not remain in its liquid they will expand to become the form of steam and this will cause you severe  internal edema all over the body, then swelling body even up to twice the normal size . But this will  not be enough steam to blow up and skin but it is likely that you will be disturbed.

2-the combustion:
 One day at the beach and you're exposed to the sun may cause you a group of burns in your body and  now imagine you are and you are exposed to the enormous power of the sun without the ozone layer  that protects us from harmful ultraviolet radiation. This effect would be devastating to the human  body.

3-choking:
  When a person is exposed in space, it will be deprived of oxygen completely, but not in the way you   think. This phenomenon is known as "hypoxia" it without the atmospheric pressure of the planet, the   oxygen content in the blood will try to go out and this will cause stop the heart and blood vessels,    and then to the muscles and vital organs, you will not be able to oxygen breathing again and here         lies the biggest problem , and in addition to that the effect of this suffocation is will turn your skin     color to blue and thus the person can withstand only 10 seconds and then die.

4 -rapid freezing:
 On a hot day, our bodies produce sweat to relieve the heat, the sweat evaporates from the surface of  the skin thus increase our energy then cooling us.
 But this effect is greatly exaggerated in outer space, usually air humidity reduce the degree of this  cooling because it is difficult to evaporate sweat in the air saturated with water. But for the dark  vacuum of space there is no moisture and this allows to accelerate cooling by evaporation exposed to  any body fluid. The eyes water and your mouth and your respiratory frozen as a result.

5- blocking the blood vessels:
 The low pressure in the space will prevent the oxygen to remains in your blood, this vacuum will do  the same thing with other gases as liquefied nitrogen "nitrogen", it will cause  small nitrogen bubbles  surround all the blood vessels. Among the side effects of the small bubbles that it will cause you  excruciating pain in the joints but it's worse is that these bubbles may cause blocking in the veins and  arteries and its presence in the brain cause a stroke then its presence in the heart will cause sudden  heart failure and death.

6- lowering the blood pressure:
 you can tell  now that the space horrible effect on the human body externally and internally,  Distension ,then burning ,choking and freezing, after all this your body try  to maintain normal blood  pressure, for example, can an ordinary person produce enough energy to drink a glass of soda by a  small tube normal, but what if the size of this multiplier tube 10 times? The heart will not be able to  pump blood to the blood vessels and from here, the blood pressure will drop rapidly until it reaches  zero and then die.

7-deadly pulls :
  One fatal mistake may shoot you out of the spacecraft and you'll want another deep breath to get         oxygen, you might think that the additional air may help you stay another minute, but the truth will     be quite the opposite, the air stay in your lungs and you're in a vacuum will cause an explosion in   your lungs
-The expansion of the air in the low pressure environment will make your lungs explode as ballon, if you find yourself in such a situation you would be
  Wise to want to breathe another and you are in the low-pressure environment?
